Chiral spirolactones, including spiropropyllactones, spirobutyrolactones, and spirovalerolactones, are important heterocyclic frameworks that attracted the atte

Indole derivatives are the most common heterocycle compounds present in nature, for this reason, they have been referred to as 'privileged structures'. In fact,
